freebsd stable - Nov 2004 - netstat -finet not working after upgrading to 5.3-STABLE

I started with a fresh 5.3-RELEASE install and then upgraded the kernel
source to 5.3-STABLE before installing a new kernel. I now find that netstat
fails to show any Internet sockets ('netstat -finet' and 'netstat
-ptcp'
give nothing, 'netstat' shows only Unix domain sockets)

I didn't do a buildworld/installworld, but I've tried a make / make
install
on netstat itself, and also on the libraries it depend on (libkvm, libipx
libnetgraph, libutil) but it still doesn't work. It also depends on libc,
but I've not rebuilt that on the basis that nothing significant seems to
have changed recently:

Another machine which I have, running 5.3-RELEASE, has a working netstat,
and that's also compiled without INET6.

My kernel does have 'device mem' in it (I only removed INET6 and
unnecessary
device drivers), and a search on Gnats, and FreeBSD-current/questions
doesn't
turn up any answers. I see nothing recent in /usr/src/UPDATING.

Any other suggestions where I can look to fix this? Do I really have to do a
buildworld?

Thanks,

Sorry, I meant to say 5-STABLE. The release tag is RELENG_5 (I just used
/usr/share/examples/cvsup/stable-supfile)

Cheers,

Brian.
